Abstract (en)
[origin: US2010265874A1] Providing for wireless communication involving supplemental wireless nodes is described herein. By way of example, prior signaling is employed between a macro base station and a set of associated supplemental nodes to support pending wireless communication with a user terminal In some aspects, the prior signaling can include control or data traffic transmitted to or received from the user terminal. In addition, the supplemental nodes can synchronize transmission or reception of the control or data traffic transmissions with similar transmission or reception of the macro base station. In some aspects, the supplemental nodes can also replicate pilot signal transmissions on OFDM symbols employed by the macro base station for pilot signals, to give consistent downlink channel for both traffic and pilot signals. Accordingly, the user terminal observes consistent pilot transmissions over various time slots, as well as concurrent traffic transmissions that can generally be decoded with a common reference signal.
